Description

The present invention relates to a wall system for building walls.

A first embodiment of the invention relates to a wall system which serves as a wall covering. In the case of wall cladding for building walls, there is often the need to erect the wall cladding or to connect it to the building wall only some time after the building wall has been created. The building wall can, for example, be an enclosure of a building consisting of natural stones that are layered on top of one another. If this building wall has become unsightly as a result of the weather, it can make sense to cover the enclosure with wall cladding instead of replacing it completely. It is also possible to use the wall covering according to the invention as a facade for a building wall. In this embodiment, the building wall forms the rear wall within the meaning of claim 1.

The wall cladding according to the invention consists of several panels placed one on top of the other in front of the building wall or the rear wall. Another structurally identical plate is placed with its lower plate edge on the upper edge of a plate that is set up essentially vertically. At least one plate edge of each plate has a U-shaped cross section. A longer U-leg is arranged on the side of the wall cladding facing away from the building wall or the rear wall. Correspondingly, the shorter U-leg is arranged on the side facing the building wall or the rear wall. In this way, the respective upper plate stands on the upper edge of the longer U-leg. A groove is left free between the two U-legs.

In an alternative embodiment, the plates are arranged next to one another. In the case of panels arranged next to one another, one of the panels abuts with its left side edge against the right side edge of the respectively adjacent panel. According to the invention, one of the side edges again has the above-mentioned U-shaped cross section with a longer U-leg and a shorter U-leg. The plate with the plate edge with a U-shaped cross-section thus rests with the edge of the longer U-leg on the respective adjacent plate. A groove is left free between the shorter U-leg and the plate edge of the adjacent plate.

In both versions, this groove serves as a receptacle for a retaining leg of an L-shaped anchoring part. While one L-leg, namely the retaining leg, engages in the groove between the U-legs of the plate, the other L-leg serves as a fastening leg. The fastening leg projects in the direction of the building wall.

For the implementation of the invention, panels are preferably used in which two opposing panel edges have the asymmetrical U-shaped cross section described above. An embodiment is also conceivable in which all the panel edges have the asymmetrical U-shaped cross section.

In a further embodiment of the invention, a T-shaped anchoring part is used instead of the aforementioned L-shaped anchoring part. The T-longitudinal limb then serves as a fastening limb, while the T-transverse limb forms two retaining limbs which each engage in the grooves between the U-limbs of two adjacent plates. These plates can stand on top of one another or be arranged next to one another.

In a basic version of the invention, the fastening leg is designed so that it serves as a direct fastening of the wall cladding to the building wall or the rear wall. For this purpose, the fastening leg is preferably designed as a dowel or anchor that can be introduced into the building wall or the rear wall.

The further embodiment relates to a wall system in which the rear wall also consists of several panels placed on top of one another or placed side by side. Again, the plates are identical. At least one plate edge of this rear wall also has a U-shaped cross section with a longer U-leg and a shorter U-leg. A retaining leg of an anchoring part engages in the groove formed between these U-legs. In the embodiment of the wall system with a rear wall composed of several panels on the one hand and a front wall on the other hand, a double-T-shaped anchoring part is preferably used, the T-longitudinal leg forming the fastening leg and the T-transverse legs each engaging in the grooves of two adjacent panels Form retaining legs.

In order to be able to erect the rear wall and the front wall exactly perpendicularly or vertically in front of one another, an adjusting element is provided in a preferred embodiment of the fastening leg. The adjusting element can be designed as an adjusting screw, for example. In a simple embodiment, a thread is cut into the end facing away from the rear wall of a fastening anchor designed as a round steel, which thread into a corresponding mating thread on the fastening leg of the Anchoring part engages. However, any other conceivable adjustment element can also be used for this purpose.

In a further advantageous embodiment, reinforcement elements protrude from the side of the front wall facing the rear wall. These reinforcement elements are preferably made of carbon. This has the advantage that the plates have little additional weight due to the reinforcement elements. Reinforcement elements made of other materials, for example stainless steel, are also conceivable.

In a further preferred embodiment, the space between the rear wall and the front wall is concreted with filler concrete after the wall cladding has been completed. The filling concrete then interlocks in the protruding reinforcement, which results in a particularly durable bond between the rear wall and the front wall. The panels of both walls then have the dual function of cladding and permanent formwork.

In a preferred embodiment, the wall system - as already stated - is effective as a facade of a building, the building wall of the building then serving as the structural wall.

The panels of the wall system can consist of different common materials. Concrete panels, plastic panels or steel panels have proven particularly useful. The anchoring part can also consist of steel, light metal or plastic. Different materials can also be mixed. In particular, it is possible to manufacture the rear wall from panels of a different material than the panels of the front wall. The invention makes it possible to realize any optics on the respective outer sides of the panels, for example a brickwork optic or clinker brick optics.

The tongue-and-groove system formed by the grooves and the retaining legs has the advantage that a certain tolerance compensation between the rear and the front wall is guaranteed.
